Application J une 26, 1947, Serial No. 757,226

This invention relates to Windows, and more particularly to aconstruction involving metal, and it is among the features of theinvention to provide a construction adaptable to new or old buildings,and in the case of the latter to suitably fit irrespective ofdistortions as commonly found in window openings in the Walls of oldbuildings. Sash-guide means is provided moreover, which is not too loosenor too tight for proper raising and lowering of the sashes. Otherobjects and advantages will appear from the following description.

To the accomplishment of the foregoing and related ends, the invention,then, comprises the features hereinafter fully described andparticularly pointed out in the claims, the following description andthe annexed drawings setting forth in detail certain illustrativeembodiments of the invention, these being indicative, however, of but afew of the various ways in which the principle of the invention may beemployed.

In said annexed drawings Fig. 1 is an inside elevational view of awindow embodying the present invention;

Fig. 2 is a section taken on a plane clear of the inside trim and stops,as at line II, Fig. 4, and illustrating how my construction sits into adistorted window opening as of an old building;

Figs. 3, 4 and 5 are enlarged detail sections taken on planessubstantially indicated by lines IIIIII, IVIV and V-V, Fig. 1;

Figs. '6 and 7 are similarly detail sections taken on planessubstantially indicated by lines VI-VI and VII-VII, Fig. 1;

Fig. 8 is an enlarged perspective view showing the assembly of an uppercorner of the sashguide;

Fig. 9 is a fragmentary perspective view showing a mode of attachment ofthe insert framing in wood supports; and

Figs. 10 and 11 similarly illustrate forms of attachment in brick andblock constructions.

In general, the invention provides insertframing, which in the form ofrails 2, 3, Figs. 6 and 5, and stiles 4, 5, Figs. 3 and 4, these beingof metal, are attachable in the window opening of the building. In thecase of such an opening in a wooden building, the rails and stiles maybe secured by screws 1, as indicated in Fig. 9. These rails and stilesare provided with a stop-flange 8 at one edge, e. g. the weather side ofthe window opening, and by having such stop in the form of a furtherre-bent margin 9, a recess is provided for the reception of a suitablepacking Ill. With some resiliency in the packing, as may be 1 Claim.(01. 189-72) had for instance with packing involving rubber orrubber-like material, with or without fiber reinforce, an adjustabilityin the seating of the sash-guide G results, and distortion such as foundin the window openings of old buildings may be compensated for in theseating of the sash-guide, and a weather-tight joint packing is alsoassured.

"The sash-guide is also of metal, hollow, and may be formed of opposedouter and inner telescoping channels II, l2, as for the stiles and toprail, and the outer and inner channels I I, [2 for the bottom rail, theoverall dimensions being uniform. The inner channels may be of lightergauge metal than the outer. A peculiarity of the inner channels I2 isthat they are provided with grooves M which have an arcuate-base l5 andwhich provide resiliency in the walls of such grooves for receivingtongues or ribs l6 which project along the stiles of the window sashesS. The latter also desirably are of metal, and while they may be ofsingle-glazed character, generally double-glazing is preferred, and forsuch the sashes may be formed of nested channels ll, it having flangesI9, 20 to somewhat resiliently grip the panes of glass, suitable sealingmaterial being interposed between the glass and the metal. If themetallic elements as set forth be made of aluminum, brass, stainlesssteel or the like, rusting or corrosion can be eliminated, alsonecessity of painting.

The sash-guide, thus as a rectangular frame to be set into the openingand engage against the packing I0 in the flange of the insert framing,may carry the upper and lower sashes U, L, as a convenient unit. Forinsertion of the sashes, the sash-guide allows of suflicientdisassembly, as illustrated at Fig. 8, the holding screws- 25 beingarranged to pass through openings in the ends of the stiles and intothreaded openings 26 in suitable lugs or cleats 2! carried in the endsof the adjacent rails. Thus, by sufficient spreading of the jointbetween stiles and rails of the sash-guide, the sashes may be positionedtherein and the joints be tightened up. It is noticed that by theprovision of projecting ends 29 on the outer channel of the rails, andcorresponding cut-outs 30 on the ends of the stiles, an interdigitatingform of joint at the corners is attained At the-same time, an opening isleft between the end of the rails and the adjacent end of the stiles,whereby ventilation of the hollow sash-guide is secured. As suchopenings are not externally exposed but are internal, circulation of airand consequent elimination of condensation of moisture is assured in thehollow structures, access of air from the room being permitted by therelatively loose fit toward the room side as contrasted with the sealedfit at the packing on the weather side.

The sash-guide may be held in place by stops 30, 3! at the inside.Conveniently, these may be hinged to the insert-framing, and piano-typehinges 32 are particularly desirable. While the sash guide may seatunattached and be thus held by the stops, i 'iiiostcases it i sefererred to secure the sas'mguideto-the stopnat one side, as forinstance by welding to the hinge member 33 which also carries the stop30. Thereby, on swinging the free stop 3! inwardly out or the Way, theentire sash-guide with its iir'itaihdsashes U, L, may be swung inwardlyir cleaning, etc. I H

For securing the sashes, atenvememsnde 35, Fig. 7, may be mounted on thelower sash 'L,

and having a projectinfg flange 36, may seat under the upper sash U,;preferably within a protecting narrow sheath '3'! Thumb lugs 38facilitate -the moving of theslide 35 into locking or unlockingpositions with respect to the sashes, and'thumb" screws 3il-permittightening base, the wallsoi the groove 14 may resilientlyfrietionallygrip the sash tongues such as to hold the sash in anyposition without requirementci counterweights. --At the same time, byreason of the resilient engagement," the sashes may be moved up and-slown 'without undue effort.

Instead of continuing the sash grooves M in c s rfe e. lew rfi e S iseiri rrfrred t o mr e ne r c nnel wi the b 9r i nsr i gyahd r h a of thed nt s h w t a were i h e e ra t'irr n be ween. t e; e as n s u d sT ieide d wii ete form of tem. bi irtqk fi l d up hr t.

It is to be emphasized that'tvith; ample clearance or spacing betweenthe sash-guide :and the frame, as attire-indicated, a compensativefit of the "sash-guide "assured irrespective of any di s tortionin thewindow frame opening due to settling or sagging oi the building.Furtherinore, with siiehspace there is lan active air circulation"between the "sash-guide and the framing, the openings atj the top andbottom facilitating such circulation; and within the sash-guide itselfthe hollow space accessible to openingsat-top and bottom also providescirculation. Thus, with such ample circulation in together, incombination with a means for eliminating -sash-counterweights whichcomprises a transversely-flat web in the inner one of said channelmembers and a pair of guide grooves formed in it characterized bycross-section in substantially complete circle form with a narrowinterruption providing margins in opposition to each other in resilientcompression, means for engaging-the transversely-flatperiphery surfacesof the stilesoi window sashes and for laterally reinforcing said groovemargins, embodying'the integral portion of said inner channel memberweb'connectingthe grooves and the integralporticns-of the web laterallyof the grooves, and Window sashes having longitudinal tongues sliding-insuch grooves.
